It seems like the first paragraph of the descriptions of the xLAROT routines got messed up:

* SLAROT applies a (Givens) rotation to two adjacent rows or* columns, where one element of the first and/or last column/row* for use on matrices stored in some format other than GE, so* that elements of the matrix may be used or modified for which* no array element is provided.

It seems like several lines are missing between the second and third lines.
